Anlyon alternative
4 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

duos_consultar_cuotaDevuelve el plan, las consultas disponibles y el presupuesto propio de IA.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Devuelve el plan, las consultas disponibles y el presupuesto propio de IA. No genera respuestas ni consume consultas. No muestra otros clientes ni el gasto global.
Annotations the server declares

duos_crear_consultaCrea una consulta autenticada: dos análisis iniciales separados y una revisión cruzada de cada modelo.Reads text others writeCan send data outNo findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a destination (input.chat_id): what the tool writes goes there.
Description, as the server wrote it Crea una consulta autenticada: dos análisis iniciales separados y una revisión cruzada de cada modelo. Envía el texto a proveedores de IA y puede consumir UNA consulta del plan y gasto de IA. Requiere intención del cliente; no usar como comprobación gratuita de conexión. Devuelve jobId/status para consultar el resultado con duos_obtener_resultado. Reutiliza el MISMO idempotency_key UUID si reintentas la MISMA pregunta; nunca cambies el mensaje con esa clave.

Description, as the server wrote it Recupera únicamente un trabajo propio creado antes. No vuelve a llamar a modelos ni descuenta consultas. Si sigue pendiente, respeta pollAfterMs antes de volver a leer. Un error no es un resultado completo.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write1
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out1
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [],
"ask": [
"mcp__duos__duos_consultar_cuota",
"mcp__duos__duos_crear_consulta",
"mcp__duos__duos_obtener_resultado",
"mcp__duos__duos_listar_consultas"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as duos. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
